Just rewired with all new HDMI cables into a new Pioneer receiver. All has worked great for a week. Worked fine earlier today. Now, nothing. I am not getting any picture, nothing, when I try to watch Blu-ray's. Nothing comes up. Just get a blue screen. "HDMI" is flashing on the front display panel of my Oppo BDP 93. Checked the cables. All firmly in place. I must have hit something on the remote when I last used the player earlier today. I was in the setup screen briefly. Since I can't bring up the Oppo's setup screens on my TV, how can I check to see how the player is outputting a signal? Is there a button on the remote that I can press to reset the player? Anyone have any ideas? Thanks!
